CVE-2026-32508Network attack vector

Object injection via unsafe deserialization

Published Mar 25, 2026 · Updated Mar 25, 2026

Deserialization of untrusted data in Mikado Themes Halstein before 1.8 allows attackers to inject arbitrary PHP objects. Neither the CNA record nor its referenced advisory identifies the vulnerable code locus or the serialized input that reaches it. Published assessments disagree on whether authentication is required; further impact requires a usable POP chain in the WordPress installation.
